The locations of these events are classified using the Flinn-Engdahl regions. John Milne developed an early tool for studying these events. A law providing for the probability distribution of these events is partially named for Beno Gutenberg. These events frequently occur in areas named after Wadati and Benioff. The intensity of these events is measured using the Mercalli scale, while frequently these events cause the most damage at their epicenters. For 10 points, name
The locations of these events are classified using the Flinn-Engdahl regions. John Milne developed an early tool for studying these events. A law providing for the probability distribution of these events is partially named for Beno Gutenberg. These events frequently occur in areas named after Wadati and Benioff. The intensity of these events is measured using the Mercalli scale, while frequently these events cause the most damage at their epicenters. For 10 points, name these events once measured with the Richter scale, which produce devastating seismic waves.
